I have no idea how loud those exhaust are on a KFX 400, but this response will bump your question back to the top of the list.

Prairie 700 with HMF Penland Series full system -- 96 dB at idle; 112 dB at wide open throttle

YFZ 450 with HMF full system -- 90 dB at idle; 123 dB at wide open throttle

DS 650 with HMF slip on -- 98 dB at idle; 130 dB at wide open throttle

130 dB is loud by the way.
